iTextSharp, doesnt support arabic?

Question

I wanted to export an arabic data listed in a dataGridView.

so i used iTestSharp for this.

PdfPTable pdfTable = new PdfPTable(dataGridView1.Columns.Count);
                        pdfTable.DefaultCell.Padding = 3;
                        pdfTable.WidthPercentage = 100;
                        pdfTable.HorizontalAlignment = Element.ALIGN_LEFT;
                        iTextSharp.text.Font fts = new iTextSharp.text.Font();
                  
                    
                        foreach (DataGridViewColumn column in dataGridView1.Columns)
                        {
                            PdfPCell cell = new PdfPCell(new Phrase(column.HeaderText));
                            pdfTable.AddCell(cell);
                        }

                        foreach (DataGridViewRow row in dataGridView1.Rows)
                        {
                            foreach (DataGridViewCell cell in row.Cells)
                            {
                                pdfTable.AddCell(cell.Value.ToString());
                            }
                        }

                        using (FileStream stream = new FileStream("Output.pdf", FileMode.Create))
                        {
                            Document pdfDoc = new Document(PageSize.A4, 10f, 20f, 20f, 10f);
                            PdfWriter.GetInstance(pdfDoc, new FileStream("123", FileMode.Create));
                            pdfDoc.Open();
                            pdfDoc.Add(new Paragraph("ID:"));
                            pdfDoc.Close();
                            stream.Close();
                        }
